#OpenCypher
What they reported:
- p99 retrieval 10.7s → 140ms
- Recall@8 roughly doubled
- HA without a license gate
- openCypher: port, not rewrite

Their own caveat: much of the speedup was finally having a real vector index. Fair.

I already love #BlueSky for being a platform for those specific technical questions and discussions 🧑‍🔧

btw - Any thoughts on the use of #Graph technology? Do you use #SAPHANA 's proprietery #GraphScript or its #OpenCypher implementation? Where do you see immediate advantages of #GQL?
Now since we have ISO GQL since April this year - are there any efforts by SAP to implement it to cater to the graph engine embedded in HANA DB and replace the proprietary graph script? #SAP #ABAP #AI #CAUSALAI

Amazon Neptune Graph Explorer Introduces Native Query Support for Gremlin and openCypher
Today, we are excited to announce the launch of a new feature in Graph Explorer that enables users to write and execute native Gremlin and openCypher queries directly within the interface. This enhancement empowers data scientists, developers, and database administrators to seamlessly interact with their graph databases using their preferred query language, eliminating the need for additional tools or interfaces. With this update, users can now leverage the full expressive power of both Gremlin and openCypher to traverse complex relationships, perform advanced pattern matching, and extract valuable insights from their graph data while enjoying the intuitive visual environment of Graph Explorer. To get started, create a new Notebook from the Amazon Neptune console, and start the Graph Explorer from the Notebook actions menu. You can also contribute to the graph-explorer GitHub project https://github.com/aws/graph-explorer. For more information on how graph-explorer works with Amazon Neptune, see the https://docs.aws.amazon.com/neptune/latest/userguide/notebooks-graph-explorer.html.
